WAVEGUIDE ARRANGEMENT

摘要

The invention relates to a waveguide arrangement (10) comprising a substrate (20) and at least one strip-shaped waveguide made of a wave-guiding layer material (30). The strip waveguide extends strip-like in a longitudinal direction and can guide waves in its longitudinal direction so that the wave propagation direction corresponds to the longitudinal direction of the strip waveguide. The refractive index of the substrate (20) is greater than the refractive index of the layer material (30). In order to guide waves vertically, the strip waveguide forms a waveguide bridge (60) which is located above a recess (100) in the substrate (20) and which is at least partially spatially separated from the substrate (20) there.
